To use full debugging features on a dump file, Visual Studio needs:

With Just-In-Time Debugging enabled, you can attach the Visual Studio debugger to a crashed process outside of Visual Studio, and then save a dump file from the debugger. While you are debugging a process in Visual Studio, you can save a dump when the debugger has stopped at an exception or breakpoint. Dump files without heaps save the values of stack variables only. The loaded binaries must exactly match the ones running during dump creation. Visual Studio can load symbols from a dump file with a heap, even if it can't find an app binary.ĭump files without heaps are much smaller than dumps with heaps, but the debugger must load the app binaries to find symbol information. Visual Studio also saves the binaries of loaded native modules in a dump file with a heap, which can make debugging much easier.

For example, compiler inlining of functions can result in unexpected call stacks, and other optimizations might change the lifetime of variables.ĭump files may or may not have heap information.ĭump files with heaps contain a snapshot of the app's memory, including the values of variables, at the time of the dump.

A full user-mode dump is not the same as a dump with heap.ĭebugging dump files of optimized code can be confusing. Visual Studio can't debug dump files saved in the older, full user-mode dump format.

To debug kernel-mode dump files or use the SOS.dll debugging extension in Visual Studio, download the debugging tools for Windows in the Windows Driver Kit (WDK). It can also debug dumps of managed apps from ARM devices, but only in the native debugger. Visual Studio can debug dump files of native apps from ARM devices.

Testers also create dumps to save crash or unresponsive program data to use for more testing. You can use a dump file from a customer's machine when you can't reproduce a crash or unresponsive program on your own machine. Although you can't continue execution, you can examine the stacks, threads, and variable values of the app at the time of the dump.ĭumps are mostly used to debug issues from machines that developers don't have access to. Opening a dump file with a heap in Visual Studio is something like stopping at a breakpoint in a debug session. A dump with heap information also includes a snapshot of the app's memory at that point. A dump file is a snapshot that shows the process that was executing and modules that were loaded for an app at a point in time.
